Background:
You are a developer for LitWare, Inc., a game development company. You are developing a backend service for an online social gaming platform named GamerData. The game is built around point generators, which are associated with physical landmarks. Players claim point generators which give them a set amount of points per day.

Business Requirements:
Mobile App The game itself runs on various mobile devices and is developed by Tailspin Toys, a company that specializes in mobile game development.
The mobile app will periodically make calls to the GamerData service to find the five closest point generators that are located less than the specified distance from the player’s current location. If no point generators are found, the search distance increases until one is found. The mobile app shows all the point generators owned by each player.
The mobile app allows for each player to search for claimed point generators by player name. This search does not require exact spelling of names. The details for each claimed generator is shown in the app.
When a player claims a point generator, they should receive an email notification. An Azure Function named EmailPlayer has been developed to email players with details about recently claimed point generators.

Sponsors: The platform allows business to sponsor point generators within a business location.

Reports: A report named Daily Sponsor Report must be generated each day at midnight. The report must contain a section for each sponsor. Each sponsor section must contain two subsections.

The first subsection of the report contains the names of the point generators for that sponsor, ordered by the last time the point generator was claimed. The second subsection contains the current owners for each of the point generators for the sponsor. Generation of reports must not impact the GamerData service.

Technical RequirementsGamerData Service: All data for the GamerData service is stored in an Azure DocumentDB instance named GamerData. Business and players interact with the service by using a REST API.

The REST API must: Produce valid Swagger API specifications for non-obsolete actions. Be optimized for loading specific point generators. Follow REST best practices. Include appropriate terms of service.
Costs for all Azure services must be minimized.

Build and Deployment: The GamerData service will be deployed to Azure in a private VNet. SecuritySponsors have accounts in an Azure Active Directory (Azure AD) with business-to-consumer (B2C) enabled named litwaregamerdata.onmicrosoft.com managed by Litware, Inc. for both GamerData and LitWare, Inc. services. Only Litware, Inc. developers and automated testing tools should be able to directly access the GamerData service.

All other use of the service must be through Azure API Management. A description of the security practices used during development, available on Microsoft SharePoint, must be available to users of the API under the terms of service.

Reporting Azure Search will be used as the source for running reports. The properties of indexes in Azure Search must match the names of the properties in DocumentDB.Performance: The Azure DocumentDB must not be used for reporting purposes. All services must perform queries in the data store when possible.

CASE STUDY Background: You are developer for Fabrikam, a company that specializes in payment processing. Fabrikam is developing a solution to process payments for various events, such as music concerts. You develop an ASP.NET MVC website that is hosted in Azure to support an upcoming music concert. The music concert is expected to generate a large volume of ticket sales in a short amount of time.
The website uploads information to an Azure storage queue. A worker role in Azure retrieves information fromthe queue and generates the concert tickets in a PDF file format after the financial transaction is approved.
You observe a delay between the time the website adds a message to a queue and the time it becomesavailable to read from the queue. After examining the queue, you determine that no queue messages have aDequeueCount value greater than zero. The website does not throw any errors.

Business Requirements Payments: The music concert website must be able to submit event payment information for processing. The website must remain responsive while submitting payment information. Customers must be able to add notes about their orders to a free-form control on the website. These notes must be submitted with the payment when the customer submits an order.
Customers often enter notes that exceed 7 KB in size.Technical Requirements Payment Submission and Processing: Event payment information must be sent from the website to a Windows Communication Foundation (WCF)service worker role. The worker role must submit the information to the payment processor in JSON format.

Payment processing you have the following payment processing requirements:If the number of messages in a queue goes above or below a specified threshold, worker role instances must be created or deleted as needed. This process must be completed by using the least amount of effort.It must be easy to reconfigure role instance thresholds. Payments must be retrieved from the queue in the maximum batch sizes that are allowed by the queue and pulled from the queue for 5 minutes. The payment queue must not be re-created when processing payments. During single Payment processing, the number of tickets available for an event must be updated.
The update operation must be retried for 30 seconds or 5 retry attempts, whichever occurs first. Each retryshould pause for at least two seconds and for one second longer than the previous attempt. If the updatefails, the payment should be placed in the poison queue.

Storage You have the following storage requirements: Payment information must be stored by using Azure Queue storage. Connection to the Azure storage account has been established in a configured setting named StorageConnectionString, which is configured for the web and worker roles.
A payment processing queue and a poison payment queue must be used when processing payments.
Azure Queue message content must be XML-safe and UTF-8 encoded.
An Azure storage account must be established for diagnostic information in a configured settingnamedDiagnosticsStorageConnectionString, which is configured for both the web and worker roles.Security and Monitoring:Security: The web role must be secured by using HTTPS.Monitoring :you must collect diagnostic data for both the web and worker roles by using the Diagnostics module.
Diagnostics configuration changes must not require the code of the roles to be rebuilt.
The diagnostic data is used for debugging and troubleshooting, measuring performance, monitoring resource usage, traffic analysis and capacity planning, and auditing.Performance testing must evaluate the roles under normal and stress conditions without incurring changes for running Azure. Memory allocation, function time, and multithreading concurrency issues must be evaluated.Deployment:
You purchase a custom domain name fabrikamfunding.com to host the website, web role, and worker roles.
You must deploy an HTTPS certificate with the web role, and you must update associated configuration files accordingly.
Web role and worker role instance sizes must be specified as Medium. You must deploy one web role instance named FabrikamFundingPaymentGenerator, and worker role instances namedFabrikamFundingPaymentProcessor.Application Structure: Relevant portions of the app files are shown below. Line numbers are included for reference only and include a two-character prefix that denotes the specific file to while they belong.
The SendMessageAsync method of the QueueManager class occasionally throws errors.You need to correct the errors.What should you do?
A. Update the QueueManager to use the Put Message operation of the Queue Service REST API. Use HTTP compression for all calls made to the REST API.
B. Encode the notesfield content by using UTF-32 encoding.
C. UpdateSendMessageAsyncmethod of the QueueManager class to store the notes field in BLOB storage. Update the EventPaymentclass to store the BLOB uniform resource identifier (URI). Extract the notes BLOB information by using the BLOB URI in the ProcessMessagesAsyncmethod of the QueueManager class.
D. Update the notesfield to a byte array. Binary encode and decode the notescontent when sending or receiving an EventPaymentclass.Continue reading “You are developer for Fabrikam, a company that specializes in payment processing….”→
